Five projects by ZHA shortlisted for World Architecture Festival 2021

Five projects by Zaha Hadid Architects (ZHA) are shortlisted
for the World Architecture Festival (WAF) Award 2021; Leeza SOHO, Beijing in
the ‘Completed Building – Office’ category; One Thousand Museum, Miami in the
‘Completed Building – Housing’ category; Niederhafen River Promenade, Hamburg
in the ‘Urban Context – Landscape’ category; Beijing Daxing International
Airport, Beijing in the ‘Completed Building – Transport’ category; and the Al
Janoub Stadium, Al Wakrah in the ‘Completed Building – Sport category.

The World Architecture Festival is dedicated to celebrating,
sharing and inspiring outstanding architecture, with the WAF Awards at the
heart of the festival.

Leeza SOHO’s Beijing site is diagonally dissected by an
underground subway service tunnel at the intersection of five new lines
currently under construction on Beijing’s Subway network. Straddling this
tunnel, the tower’s design divides its volume into two halves enclosed by a
single facade. The space between these two halves extends the full height of
the tower, creating the world’s tallest atrium at 194m which rotates as the
tower rises to realign the upper floors with Lize road to the north.

One Thousand Museum’s 62-storey concrete exoskeleton – a web
of flowing lines integrating structural support with lateral bracing – reads
from top to bottom as one continuous frame. Columns at its base fan out as the
tower rises to meet at the corners, forming a rigid tube highly resistant to
Miami’s demanding wind loads; its curved supports creating hurricane resistant
diagonal bracketing. “The design expresses a fluidity that is both structural
and architectural,” explains project director Chris Lepine. “The structure gets
thicker and thinner as required, bringing a continuity between the architecture
and engineering.” The design incorporates GFRC form-work which remains in place
as construction progresses up the tower. This permanent concrete form-work also
provides the architectural finish that requires minimal maintenance. Behind the
exoskeleton, the faceted, crystal-like façade contrasts with the solidity of
the structure. With its frame at the perimeter, the tower’s interior floor
plates are almost column free; the exoskeleton’s curvature creating slightly
different plans on each floor. On the lower floors, terraces cantilever from
the corners, while on the upper floors, the terraces are incorporated behind
the structure.

The Niederhafen River Promenade in Hamburg by ZHA is
integral to the modernisation and reinforcement of the city’s flood protection
system and incorporates the city’s riverside walkway providing panoramic views
of the Elbe and its historic port, reconnecting its river promenade with the
surrounding urban fabric by creating links with adjacent neighbourhoods. Wide
staircases resembling small amphitheatres are carved within the flood
protection barrier at points where streets from the adjacent neighbourhoods
meet the structure; giving passers-by at street level views of the people
strolling along the promenade at the top of the barrier and views of the masts
& superstructures of ships in the Elbe.

Beijing Daxing International Airport is 46km south of the
city (20 mins by express train). Its 700,000m² passenger terminal includes a
ground transportation centre offering direct connections with the national
high-speed rail network and local train services. Echoing principles within
traditional Chinese architecture that organise interconnected spaces around a
central courtyard, the design guides all passengers seamlessly through the
relevant departure, arrival or transfer zones towards the courtyard at its
centre. 6 flowing forms within the terminal’s vaulted roof reach to the ground
to support the structure and bring natural light within, directing all
passengers towards the central court. Linear skylights provide an intuitive
system of navigation throughout the building, guiding passengers to and from
their departure gates.

The Al Janoub Stadium in Qatar was inaugurated in May 2019
by hosting the 2019 Amir Cup Final. The first new venue commissioned for the
2022 FIFA World Cup, the stadium incorporates an operable roof to shade the
field of play. Passive design principles along with detailed computer modelling
and wind tunnel testing were employed to maximise the effectiveness of the
enclosure for player and spectator comfort. Reflecting Al Wakrah’s maritime
heritage, the stadium’s design incorporates local cultural references combined
with practical responses to climate, context & functional requirements. Al
Janoub’s 40,000 seating capacity for the World Cup will be reduced to 20,000
seats after 2022 – optimum capacity as home ground to the local Al Wakrah Sport
Club professional team.
